Mutation details: A neomycin selection cassette replaced the exon encoding the IgV-like domain of the protein. RT-PCR analysis on RNA derived from spleen, thymus and LPS-stimulated B cells of homozygous mice demonstrated that no detectable transcript was produced from this allele. FACS analysis on B cells derived from homozygous mice confirmed that no functional protein was encoded by this allele.
